The aquaponic mineralization process we used in the UAE build is a great topic to discuss. When we first started that 3600 square meter raft we had only 100 fish running it. No surprise 100 fish will not run nearly an acre of plant production unless they are 200kg each. Our little 1 to 2 kg Tilapia were not enough to keep us going. So what did we do?
There has been a huge amount of speculation about how we were adding hydroponic nutrient and chemical fertilizers. At the time we were there running the farm, at start up, we published photos of what were were doing. We were using an organic pellet specific to our needs.
